Sorry mate, I have to to agree with Cap here. I don't like how tinted lights look and why would you want to reduce the effectiveness of a basic safety feature

?
If anything, the standard headlights on the Panda aren't that great to begin with (especially compared to some more modern cars).
That said, as mentioned above, that's just my opinion, I'm sure others think it looks great and I guess you could compensate for the reduced light output with uprated bulbs.
